Thepresent invention in one aspect verse ears l3 similar in outline-to theears l2 consists in a 'new' and improved locking device 'ofth'e shankand arranged in superposed position arranged to operate independentlyofthe key ,s. above them In the guideway formed in the and to bereleasedas part of the usual blade- '-Walls of theshank slides the body 2!] of abladeclamping device which will be presently described.

'Above the ,ears I3 is located the bottom plate 14 of the head irame ofthe razor and this is provided at opposite sides with uprightsidemembers [5. These side members are'roughly trireference may be hadfor complete details of the blade seat and blade holder.

Next above the base plate l4 comes a stationary sheet metal member inwhich is formed the guard IS. The blade seat 40 is formed by an innerportion of this member. In one side member I5 is formed a substantiallyrectangular notch l1 providing a passage into the interior of the razorhead for the magazine key 38 which, as suggested in Fig. 1, may beentered through this passage in approximately horizontal position andwhich locates the magazine properly in position. to deliver fresh bladesone at a time to the blade holder. The side member is also provided witha square aperture [8 for receiving a pilot spur on the magazine. I

The movable element of the razor comprises a blade-clamping device forholding the blade securely in shaving position on the blade seat. The

body of this device has already been referred to as the slide arrangedto move freely in an inclined guideway formed in the shank of the razor.At its rear end the slide merges into a downturned finger piece 2| bywhich the device may be retracted. At its forward end the slide 20merges into an upstanding vertical wall 22 fitting into andsubstantially filling the portion cut-out from the front wall of theshank H. The vertical wall 22 merges at its-upper end into a downwardlyand forwardly inclined portion 23.

having a square aperture 28 therein. The portion 23 in turn merges intoa hooked portion 24 extending upwardly and rearwardly in spaced relationto the portion 23. The portions 23 and 24 together with an internal edgeor surface inside the razor head constitue a guideway for the receptionof the key 38 of the magazine which is shown in dotted lines in Fig. 1.The hooked portion 24 is centrally disposed in the clamping device, asshown in Fig. 1, and at each end thereof is provided an upwardly andforwardly extending arm 25. The arms are curved rearwardly above theblade seat and support a transverse blade-clamping bar 26 at itsopposite ends. Both of the upstanding arms are provided with rearwardlyor inwardly extending guide arms 21 which slide against the end edges ofthe stationary guard. Within the shank II is provided a torsion springconnected to the slide 20 of the blade-clamping device and tending atall times to move it rearwardly, that is to say, into the blade-clampingposition shown in Fig. l.

The-magazine herein shown is generally rectangular in shape and designedto hold a stack of ten or twelve blades which are to be delivered one byone through a slot in the left end of the magazine as seenin Figs. 2 and3. The bottom plate 30 of the magazine is extended forwardly to providea key 38 and this key is shaped to enter the passage I! in the razor andto retract the blade-clamping device 2025. The key 38 projects from theleft-hand end of the magazine which is concealed in the viewsof thedrawing. The magazine is. also provided with a square pilot spurconstructed and arranged to enter the square front wall of the magazine.

aperture I 8 in the upright side member I5 of the razor head and thus toassist the key in properly locating the magazine and prevent it fromtwisting on the key. As shown in Fig. 2 a flat leaf spring 32 underliesthe stack of blades 3| and holds the uppermost blade in the stackyieldingly against the roof of the magazine. A feed slide 33 is arrangedto reciprocate upon the magazine and is provided with an internalextension for engaging the uppermost blade of the stack and advancing itto and through the outlet slot of the magazine.

To the bottom of the magazine is attached by means of a rivet 35 a sheetmetal member 34.

This has an upstanding flange portion 38 with an inclined edge cam facesloping upwardly and rearwardly and normally disposed against the Italso merges into a projecting dog or pawl 31 provided with a tooth orextension arranged to fit into the aperture 28 already referred to asbeing formed in the plate 23 of the blade-clamping device when thelatter has been moved outwardly to its blade-releasing position. Thefeed slide 33 has rounded corners and a downturned flange arranged totravel in a path on the front wall of the magazine in which it engagesthe inclined face of the flange 36 of the locking mechanism, forcing itdownwardly and retracting the dog 31 from engagement with the lockingrecess 28. In this movement the spring locking piece flexes about therivet 35 as an axis.

In using the razor and magazine above described the key 38 of themagazine is first inserted in the passage I! of the razor head andpushed fully home until the end of the magazine is arrested againstupright side member I 5 of the razor head. In this movement the keyretracts the blade-clamping device 2026,-releasing the used blade in theblade holder and bringing the locking aperture 28 into registration withthe locking dog 31 which, up to this time, has been yieldingly pressedagainst the portion 23 of the blade-clamping device. At the conclusionof these two movements the tooth of the dog enters the locking recess 28and the magazine and razor head thus become positively'locked againstseparation. Incidentally, the blade-clamping device is also positivelylocked by the dog 31 in its retracted or forward position. With themagazine and razor thus interlocked the user advances the feed slide 33toward the left as seen in Fig. 2, thus feeding the uppermost blade inthe stack into the blade holder of the razor head where it encountersand ejects the used blade in reaching its shaving position. As the feedslide approaches the end of its feeding movement it encounters, theinclined cam surface of the flange 36 of the locking device, depressesit and causes disengagement of the dog 31 from the locking recess 28thus freein the magazine for separation from the razor head, but onlyafter it has insured complete and safe delivery of the fresh blade tothe razor. Disengagement of the dog 31 from the recess 28 also releasesthe bladeclamping device which is thereupon immediately moved rearwardlyby its spring.

After the magazine has been separated from the razor the feed slide 33is moved toward the right hand end of the magazine preparatory toengaging and feeding the next blade from the stack. In this movement theflange 36 is released and the member 34 again springs into contact withthe bottom of the magazine and thedog 3'| moves into operative positionin readiness to enter the recess 28 when the magazine is next presentedin blade-delivering position.
